.EXCAVATING AND SCOOP SHOVEL.

Application filed May is, 1925. Serial no. 30,921.

To all whom it may concern:

Be it known that 1, 7011mm. S. KELLY, a citizen of the United States, residing at Chicago, in: the county of Cook and State of Illinois, haveinvented certain new and l useful, Improvements in Excavating and Scoop Shovels, of which the following" is aspecification.

his lnvention has to do with improvements in power-operated shovels for excavating, and particularly for scoop work. The

shovel herein disclosed is particularly in-v tended foruse in that class of work in which the shovel is first given a more or less horizontal movement to scoop up the material,

and is afterwards raised'so as to carry the material to a desired point where it is dumped.

The main object of the invention is" to provide a device of the foregoing character whichis so constructedthat' in the horizontal scooping operation, it will naturally tend to bite into the surface of the earth so as to ensure a speedy filling of the scoop, without, however, being subject to an excessive amount of biting actionsuch as would tend to jam the front of theshovel and tend to cause it to turnover.

A further feature of the invention relates to the provision of an extremely simple construction and one which may, if desired, be made from a single casting or asa solid rigid structure of the built-up form.

Another object of the invention it to provide a device of the foregoing character which has its'front portion so constructed that it will act very much as a plow in entering into and breaking up the materlal sought to be excavated. This will not only improve the scooping action itself, but will also considerably facilitate the operation of the device and make it possible to do its work at a greatly reduced'power consump tion.

Another feature of the invention relates to the provision of improved means for sustaining the front portion of the device when i it is raised. so as to retain the material therein until the device has been moved to the proper dumping position.

Other objects and uses of the invention will appear from a detailed description of the same which "consists in the features of construction and combinations of parts here inafter described and claimed. a

Fig. 2 shows a plan view corresponding to Fig. 1'; and

Fig. 3 shows a front-elevation corresponding to Figs. 1 and 2.

My improved scoop includes generally a body 4 having a floor 5 the rear portion of whichis curved upwardly as shown at 6 in Fig. 1, and continues on upwardly to establish a back wall 7. as shown in Fig. 3. The extreme upper edgc'of this back wall is then preferably curved forwards as shown at 8 so as to prevent the material from overflowing at the upper edge of the back wall portionduring the scooping operation.

figures to establish a plow point or the like 11. This plow point has its extreme front pointed portion 12 turned down somewhat as best shown in Figs. 1 and 3, so that it will bite into and open up the furrow of m aterial which is to be taken into the scoop. Immediately behind this pointed portion there is an upstanding arm 13 which reaches up to a position somewhat above the center of the height of the scoop and is then carried forwardly in a substantially horizontal direction.that is parallel to the flat portion 5 of the floor, as a beam 14in Fig. 1. This horizontally extending beam 14 preferably reaches to a position somewhat in advance of the cutting point 12, its extreme front portion being provided with a suitable eyelet 15 for the tow and control ropes. The front edge of the arm 13 is preferably somewhat sharpened as clearly shownin Fig. 3, so as to assist in breaking the excavated material and throwing it to both sides of the arm so that the two sides of the scoop will be equally filled.

On a

provide the pins 16 and 17 to which may be attachedjthe lifting chains 18 and 19, re-

line aboveand somewhatbehind the center of gravity of the scoop when filled, I

portifons of these chains il8fand #19 "are brought together at a common eye to which may be attached a lifting rope or chain 21. Preferably a spacer bar "22eitte'ntlsbetween the chains 18 and 19 at a point abovethe scoop, said bar being of sulh'cie'nt length to hold the lower portionsgofthewchains absuch a degree of separation that they do not 1naterially'interfere :with the tilting 'andi 1nanipulation of theseoop itself. V

The tow ropez23, which usuallyipulls 'in a i substantially horizontal direction, may *be *c'ofnnected I to the eye by i'neans -of a chain :24. w A controlrope 2'5 also-'r'eachesfrom the 15 eye 15 upwards and backwardsratzamangle of about :60 degrees; and then :passesover a pulley 26 and again forwardlyasshownin QFig. -l. 'lhe-pulley 26 i in' turn is conveniently placed on the front end=of a shortsecti'on of'ropc" orchain127 fVlllClldS, in .turn,'-connected to the-- eye 20; already referied to.

After the" scoop is filled, it may be rai'sed by-th'e use- 0f the chainonrope 21, theten- 'sion on the control rope being regulated so as to e prevent the 'front'edgebf' the scoop from tipping sufficiently-to allow material-to bedischarged until the :desired time; then by easing oif the rope 25 the front edge of the' scoop will fall on account of the, rearward position of tl1e pivotal points 16 and 17, resulting in; a desiredzdumping.

for example,- by the use of-one' onmore drums -28'located in advance of;tl1e-.positio'n ofthe scoop itself. 7

'By providing 'aplow :poin't which inei =ges -rearwardly into a relatively thin upstanding 'forthe scoop, thematerial will be diverted laterally and evenly intobothsidesof the scoop,*andi at the sametime such fin will act like anupstandingglteel to prevent lateral "slewing of the scoop and maintain its straight line of travel when 'Cllfi-lYIl fOlfW'fild "from-a 'si-ngleycente'r connect-ion, which arrangement}obviates the necessity of using a Ffront:-ba'il;and--sideconnections of the character commonly employed in the art. i
